In a wireless communication system in which there is a propagation delay between a terminal station device and a base station device using time division multiplexing in a duplex operation system, at least one of the base station device or the terminal station device includes a delay calculating unit that calculates a propagation delay, and the base station device or the terminal station device includes a control unit that changes a frame configuration such that a standby time required for switching between the uplink frame and the downlink frame is shortened in accordance with the propagation delay. In accordance with this, a surplus standby time is shortened, and a transmission capacity can be improved.

In an embodiment a supplementary uplink (SUL) configuration method includes determining, by an access network device, a plurality of synchronization signal blocks (SSBs), wherein each of the plurality of SSBs comprises configuration information of one SUL and broadcasting, by the access network device, the plurality of SSBs on a downlink.

A method and apparatus are disclosed from the perspective of a network. In one embodiment, the method includes the network configuring a DL (Downlink) BWP (Bandwidth Part) and an UL (Uplink) BWP in a first serving cell to a UE (User Equipment). The method also includes the network configuring a paired spectrum operation in the first serving cell to the UE. The method further includes the network transmitting a first DCI (Downlink Control Information) to the UE, wherein the first DCI comprises a slot format combination indicating one or more slot format values for the DL BWP and one or more slot format values for the UL BWP. In addition, the method includes the network prevents from setting an amount of slot format values in the slot format combination in the first DCI to be not divided by a first number, wherein the first number is associated with an absolute value of a difference of a first SCS (Subcarrier Spacing) configuration and a second SCS configuration.

Systems and method for using control information to control the relay of signaling between a base station and a user equipment (UE) using a smart repeater (SMR) and/or reconfigurable intelligent surface (RIS) are disclosed herein. In embodiments, a first phase is used by the SMR with a first SS burst from a base station to identify a trained Rx beam to use with the base station, and a second phase receives a second SS burst from the base station and forwards it to a UE using a beam sweep such that the UE is enabled to provide feedback of one SSB of the second SS burst. In other embodiments, an SMR or an RIS is controlled to enable the use of an SS burst to perform a full check of all beam-wise routes between the base station and the UE, enabling feedback of a corresponding SSB selection by the UE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may obtain a time division duplexing (TDD) split configuration, for inter-node interference mitigation, that is based at least in part on at least one of a subset of compatible beam pairs of a set of beam pairs or a subset of non-compatible beam pairs of the set of beam pairs, and that indicates a first restriction duration and a second restriction duration, a beam pair of the set of beam pairs comprising an uplink beam associated with the first network node and a downlink beam associated with a second network node. The first network node may communicate with at least one user equipment (UE) based at least in part on the TDD split configuration for inter-node interference mitigation. Numerous other aspects are described.

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques and devices for uplink gap configuration. Certain aspects are directed to an apparatus for wireless communications at a user equipment (UE). The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the instructions may cause the apparatus to obtain, from a base station, a first time division duplex (TDD) configuration for wireless communications between the UE and the base station. The instructions may cause the apparatus to obtain, from the base station, an uplink gap pattern (ULGP) configuration indicating a first ULGP associated with a first time window and the first TDD.

A disclosure of the present specification provides a method for performing measurements. The method may performed by a user equipment (UE) comprise: performing, by the UE, measurements; based on that (i) the measurements are for measuring a cross link interference (CLI) and (ii) that the measurements are performed on a sounding reference signal (SRS) from a neighboring UE in a neighboring cell, adjusting a time error between a downlink reference timing in a serving cell and a SRS arrival timing from the neighboring UE. The adjustment is performed based on offset.

The present invention is designed so that, when a CP-OFDM waveform is supported in the UL in addition to DFT-spreading OFDM waveform, transmission of UCI can still be controlled adequately. According to the present invention, a user terminal has a transmission section that transmits uplink control information (UCI), and a control section that controls transmission of the UCI based on a waveform of an uplink (UL) data channel or based on indication information provided via higher layer signaling and/or downlink control information (DCI).

A laminar phased array has a first sub-array configured to operate in one of a receive mode with a first polarity and a transmit mode with a second polarity, and a second sub-array configured to operate in one of a receive mode with the second polarity and a transmit mode with the first polarity. The first polarity is physically orthogonal to the second polarity. The array also has a controller configured to control the first and second sub-arrays so that they operate together in either 1) a receive mode or 2) a transit mode. Accordingly, both sub-arrays are configured to operate at the same time to receive signals in the first and second polarities when in the receive mode. In a corresponding manner, both sub-arrays are configured to operate at the same time to transmit signals in the first and second polarities when in the transmit mode.

Methods, systems, and devices for wireless communications that support coordinated beamforming in millimeter wave (mmW) systems. A user equipment (UE) may indicate a number of supported antennas for signal reception. A plurality of transmission-reception points (TRxPs) may coordinate a beam training with the supported antennas, in determining a beam estimation for coordinated reception at the UE. The coordinated beam training may be carried over combined beams of the associated TRxPs, and may be based on co-phasing factors within a single antenna panel for each of the TRxPs. Based on the coordinated beam training, the UE may determine a matched filtering beam estimate for reception and receive coordinated beamformed transmissions from the plurality of TRxPs as part of coordinated multipoint (CoMP) transmissions.
